The Cat Covenant Ring will add Forest Hunter players who wear it to an invasion queue. Those players will be sent to invade the worlds of non-Forest Hunter players who enter Darkroot Forest to kill them.

Unlike normal invasions, the Forest Hunter invasions can be performed even by hollow players and from anywhere in the game world (except for those areas without an associated boss, such as Firelink Shrine or Gwynevere's chamber in Anor Londo). There is no level restriction, meaning someone of low level such as 40 can invade anyone, so they could be paired with a level 200. The invaders lose nothing should they fail, including their non-hollowed state. Invaders who die will be returned to the last bonfire they visited with all items, souls, and humanity intact.

Removing the ring when in the target's world will not cause the player to return to their homeworld.

Successfully killing a player as a Forest Hunter invader will raise the Forest Hunter's rank and reward them with an item.

The Cat Covenant Ring stays with the player if they leave or betray the covenant, but will not function while not formally affiliated.

If the ring is lost by any means, it will reappear in the chest behind Kingseeker Frampt after reloading an area.

It is possible to farm souls from this ring as it can never be permanently lost. Feeding it to Kingseeker Frampt will result in 1,000 souls, and the ring can then be retrieved from the chest behind him after reloading the area.
